Tim Keller nails it! (HT: Justin Taylor).
The Gospel is my nourishment. Keeping my eyes focused on my Savoir and who he is and what he has done and the fact that I now have intimacy with him 24/7/365 (yes, even while doing laundry and cleaning toilets) is what mends my broken heart and transforms my focus from an inward one to an outward one. Engaging in contemplative mind-altering states (such as centering prayer) or practicing a silence in which I watch my thoughts from a distance like watching clouds is not a discipline advocated or supported by Scripture. “Going deeper” is not some advanced spiritual technique (like it is for eastern pagan religions) but a long, slow process in which we engage God with our entire being, through His Word, and through prayer, and community, and service, and evangelism and through enjoying his ever present presence. But it all starts with the Gospel, grows through the Gospel and culminates with the Gospel.
